Have you tried to reinstall Studio? This method use great:


Eventually please check if firewall or anything like that is not blocking your connection.

Hi @Pablito,

I’m also facing similar issue. Unable to install pdf activities from manage packages. I’m using the latest stable version. My current studio version is below,

Studio 2020.2.0-beta.108 - 9/11/1953
Community License
EXE Installer

License Provider: Internal
Activation ID: UIP-c3805e19e5

Update Channel: Stable

Microsoft Windows 10 Enterprise 64-bit
.NET Framework Version 4.7.2 or later

My issue while trying to install pdf activities: Throwing this below error after loading for 15 mins…!

The feed ‘Official [https://www.myget.org/F/workflow/ ]’ lists package ‘UiPath.PDF.Activities.2.1.0’ but multiple attempts to download the nupkg have failed. The feed is either invalid or required packages were removed while the current operation was in progress. Verify the package exists on the feed and try again.

This looks like some connectivity issue. It could be causes by some internal company policies or a firewall.
